Slight rant-yes mineral oil will help you go
Moral of the story is LISTEN TO YOUR CAR!!!!!!!!
Well, in order to get my GXL back on the road after sitting for a few years one of the things I had to do was change the leaky master cylinder for my clutch. Bought a refurb, slapped it in, pumped it up and it held fine---until tonight. A few days ago I noticed that the clutch felt a little spongy but not enoough to really worry me and I ignored it. Big mistake!!!!!!!
Got in the car while downtown this evening to get something to eat and my now really soft clutch pumped up just enough for me to get into traffic and then dumped out-clutch pedal to the floor-completely. Hazard lights on, hood up, horns honking, I check the reservoir and its bone dry. My bad.
Of course its late, theres no gas station downtown, only a pharmacy at the corner. Yup, I got a quart of mineral oil(same viscosity almost, pretty neutral, oh well),filled the reservoir with it, pumped it up and voila! Now I can at least start the car with the clutch in and I can make it home.
I will drain it tomorrow, hopefully find the leak and replace it with real clutch fluid but this got me by.
Any dangers or harmful effects from using this stuff temporarily??(yeah I know it's also a laxative)

hmm..i dont think there should be any harmful effects. I wouldnt want to mix it though, so I would suggest completely flushing everything before you put more fluid in. I have even heard of people putting straight water into brake system when they ran the MC dry. Not to good because it could rust and corrode your brake lines, but if it got them home then...just remember to do a complete flush of the system.

You need to flush the entire clutch hydraulic system with alcohol NOW and remove the mineral oil. Use proper hydraulif fluid (ie. brake fluid). You've probably just killed your master and slave cylinder.
As for shifting without the clutch, if you rev match, then things will be fine.

It's a long article to explain. Briefly, this is using the accelerator to adjust engine/flywheel speed to the speed of the aft driveline. With the engine spinning the clutch and transmission gearing, the road wheels spin part of the driveline such as axles, differential, and part of the transmission. Accelerator/throttle spins the engine. If the clutch is engaged, part of the transmission can be spinning from the engine, and part of the transmission spinning from the road wheels. If their rates of spin differ when attempting a gear selection, they'll grind each other until something gives or wins this grinding competition.
The skill of matching engine to aft driveline is improved through continuous learning with driver sensitivity to engine speed, roadway speed, and gear selector/shifter (single guys might do better at this, hee haw), and clutch engagement, both upward and downward in shifting. This is often termed Double Clutching, not to be confused with multi-plate clutch assemblies. I consider the simplest of double-clutching as the natural drop in engine speed between shifting gears, when the operator briefly rests the accelerator while selecting an upper gear.
Smooth downshifts sequentially through 2 or more gears enters a degree of intermediate skill, with advanced degree of skill with heel-toe downshifting. The heel-toe combines simultaneous varied braking and clutching along with the RPM-matching of double-clutching to keep the engine in a range of peak power, conserving driveline inertia, and maintaining optimum fluid pressures.
It's also damned fun, but a fuel hog.

If any collective car group out there knows how to drive a car without a cluth pedal Its us 2nd gen'ers
...over the course of my RX7 history I can at least think of...hmmmmm 5-6 times ive had to drive my car without the 100% function of a clutch pedal.. granted one of the times was due to leaking lines..(my fault) but the others where the whonderful design (or lack there of) of the master cyclinder. New,used,rebuilt they all decide when they wanna go. regardless of location,speed, and traffic. Its giving me a whole new reason to rev match, not that going fast wasent a good reason.. but getting there is a far more practical
P.S. It never hurts to practice clutchless shifting every now and then.. it comes in handy when your forced to

What.!.!
Clutchless shifting has no effect on syncromesh wear.
Stupid question: How do you start from a light with your clutch not working? Slam it into 1st and accelerate as to not stall? I don't see how you can really rev match it. Maybe i am missing something.

Heel-toe, I thought it was impossible when I first heard about it. I can do it pretty well now. Why? Because when my engine is cold it dies if I let it idle at all. So after holding it at 1k for 30 seconds I drive to warm it up, and heel-toe keeps it running
Yes, that is my car

I have had to do the clutchless thing many times, in my poverty days I did it on one of my cars for about two weeks. The only hard part is if you totally stop at a red light you have to crank it in gear and thats bad for the starter. Then match RPMs to shift, I usually over rev then drop it in as I let off the gas. When I bought the vert. in my avatar, the clutch pedal was totally gone and when I wanted to test drive the car, the owner thought I was nuts, He said "You will never even get the car moving", well, I did... and I drove it home that day in 5:30pm traffic 20 miles to my house.
The look on his face was priceless as I drove off, I guess he was rethinking the price he had just sold his "non-running" car for.
